Sep 10, 2024 · Local coordinates cannot be mixed with world coordinates (e.g. ^ 0 ^, ^ 0 ~1), and attempting so alerts the typist, "Cannot mix world & local coordinates (everything must either use ^ or not)." So such a command fails to be parsed.

Coordinates numerically represent a location in a dimension.
Coordinate system
World coordinates are based on a grid where three lines or axes intersect at the origin point. •The x-axis indicates the player's distance east (positive) or west (negative) of the origin point—i.e., the longitude, •The z-axis indicates the player's distance south (positive) or north (negative) of the origin point—i.e., the latitude, •The y-axis indicates how high or low (from 0 to 255 (pre 1.18) or -64 to 320 (from 1.18), with 63 being sea level) the player is—i.e., the elevation, •The unit length of the three axes equals the side of one block. And, in terms of real-world measurement, one block equals 1 cubic meter. The origin point marks the zero point for the x and z coordinates. Hence, it may be thought of as the 0,0 coordinate: •X-axis = 0 •Z-axis = 0
Block position
The position of a block is actually the coordinates of the point at the lower northwest corner of the block, that is, the integer coordinates obtained by rounding down the coordinates inside the block. In Minecraft, decimal coordinates usually needs to be converted into integer coordinates by rounding down, which is called the block position of the coordinate.
Displaying coordinates
In Java Edition, pressing F3 (or Fn + F3 on Macs and some laptops or Alt + Fn + F3 on newer Macs) brings up a debug screen which gives the player's current coordinates and rotation in the upper left part of the screen. It can be disabled using the command /gamerule reducedDebugInfo true. In Java Edition, pressing F3 can also replace the crosshair with a display of these three directions: +X in red, +Y in green, +Z in blue (eastward, upward, and southward, respectively). In Bedrock Edition, the block position of the player can be displayed by changing the world options. The coordinates are displayed in a box in the top left, if the "Show Coordinates" option is turned on in the game settings screen or /gamerule showcoordinates true is used.
Relative world coordinates
When specifying coordinates, each coordinate can alternatively be expressed as a relative world coordinate, written in tilde notation (~ΔX ~ΔY ~ΔZ). A number following a tilde (~) describes an offset from execution position along one of the world axes, and a lone tilde assumes an offset of 0. For example, the position 32 blocks SSW ~10 ~ ~-30 means "10 blocks east (+X) and 30 blocks north (–Z) of here." And ~ ~ ~ means the command's current position. Relative world coordinates can mix with absolute coordinates; for example, /tp ~ 64 ~ keeps the sender's X and Z positions unchanged but teleports them to an absolute height of 64 blocks. The /execute command can update a command's current position, changing the meaning of ~ ~ ~.
Local coordinates
The other way to describe positions is with local coordinates, written in caret notation (ΔXlocal ΔYlocal ΔZlocal). Like relative coordinates, these describe positions relative to where a command is executed from, but with different directions. A number following a caret () is an offset within a moving, entity-centric frame: This coordinate system is centered at the executor's position, with +Xlocal directed to its left, +Ylocal directed upward, and +Zlocal directed in the direction the sender faces. (Note that an entity with rotation 0 0 has its local frame aligned with the world frame.) Described in other terms, these coordinates express ΔSway ΔHeave ΔSurge For example, /tp 5 teleports the player 5 blocks forward. If they turn around and repeat the command, they are teleported back to where they started. In Java Edition, pressing F3+B displays the +Zlocal direction for all entities as a blue ray centered on their heads. Local coordinates cannot be mixed with world coordinates (e.g. 0 , 0 ~1), and attempting so alerts the typist, "Cannot mix world & local coordinates (everything must either use or not)." So such a command fails to be parsed. However, this effect can be achieved using /execute rotated ~ 0 to "globalize" the y coordinate, and /execute rotated 0 ~ to "globalize" the x and z coordinates. For example, /execute rotated ~ 0 run tp 3 will teleport the player 3 blocks in forward, but at the same y level. A command's execution position, rotation, dimension, and anchor all can change the effect of using . These can be updated by the /execute command.

I keep finding myself beating my head against Minecraft's definition of local coordinates. To me local means it's position and orientation relative to the executor of a given command. In the case of a player this would mean the axes up, forward and right are defined as the player's view axes for up, forward and right instead of the world axes.
When a coordinate is written as a number, it is an absolute coordinate and refers to a specific position in the world. For example, 119 76 237 is an absolute coordinate and can refer to only one specific location in your map. Relative Coordinate. When a coordinate is written with a tilde ~ notation, it is a relative coordinate in the game.
In Minecraft game design, the player is given tools to solve problems within the context of the game world. It reduces reliance on UI, preferring instead actual interactions in the world. For example, instead of putting a mini map on the screen or having the world map accessible through menus, like in other games, it gives the player an actual map item that your character holds in its hand.
The title explains it all. Currently, in the 17w50a snapshot for Minecraft Java edition, the local coordinate type ("^ ^ ") has been introduced. While this is great and all, the ability to mix these local coordinates with relative (and even world) coordinates is not allowed. Take summoning a zombie for example: /summon zombie ^ ^ ^1
